The adjustment is applied separately for each channel. Parameters ---------- image : ndarray Input image. Can be gray-scale or in color. reference : ndarray Image to match histogram of. Must have the same number of channels as image. channel_axis : int or None, optional If None, the image is assumed to be a grayscale (single channel) image. Otherwise, this parameter indicates which axis of the array corresponds to channels. Returns ------- matched : ndarray Transformed input image. Raises ------ ValueError Thrown when the number of channels in the input image and the reference differ. References ---------- ..
